Tatsuhiro Tsujikawa 1e95c8b313 Allow always max 1024 padding for HEADERS
We need paddings regardless of payload and frame boundary to mitigate
certain attacks.

Since we handles CONTINUATION internally, we don't show FLAG_PAD_HIGH
and PAD_LOW flags of HEADERS in nghttp/nghttpd. We just show the
total paddings in HEADERS + CONTINUATION.

Tatsuhiro Tsujikawa 082876d92d Contribute flow control window for each byte PAD_HIGH and _LOW in DATA
This may help the pathological situation where window is too small.

Tatsuhiro Tsujikawa 78d202ac30 Callback based padding from application
Now previous padding options are removed and instead we added
select_padding_callback to select padding length for each frame
by application. If this callback is not implemented by application,
no padding is added.

This change also fixes the broken session_detect_idle_stream()
if stream_id is our side.

Tatsuhiro Tsujikawa ab684a9f30 Remove nghttp2_on_request_recv_callback
It is easy enough to check the end of incoming data by evaluating

Tatsuhiro Tsujikawa bbdc015e84 Call on_frame_recv_callback for DATA even if stream has been closed
This makes the callback semantics consistent with the other
frames like HEADERS/PUSH_PROMISE.
2014-01-29 21:34:48 +09:00
Tatsuhiro Tsujikawa e186e01933 Replace on_end_headers_callback with on_begin_headers_callback
Previously, there is inconsistency when on_frame_recv_callback
is called between HEADERS/PUSH_PROMISE and the other frames.
For former case, it is called before header block, in latter
case, it is called after whole frame is received. To make it
consistent, we call on_frame_recv_callback for HEADERS/PUSH_PROMISE
after its frame is fully received. Since on_frame_recv_callback
can signal the end of header block, we replaced on_end_headers_callback
with on_begin_headers_callback, which is called when the reception
of the header block is started.

Tatsuhiro Tsujikawa a3082b7c1e Remove nghttp2_on_data_recv_callback and nghttp2_on_data_send_callback
nghttp2_data is added to nghttp2_frame union. When DATA is
received, nghttp2_on_frame_recv_callback is called. When DATA is
sent, nghttp2_on_frame_send_callback is called.

Tatsuhiro Tsujikawa dba2406aba nghttp2_sesson_mem_recv: Process incoming data in streaming fashion
Now incoming data is processed in very small buffer (up to 8 bytes)
using state machine. GOAWAY debug data can get to 16K - 1, and we
don't have callback for it. Since we don't want to buffer that
amount of data just for debugging, we currently discard it.
This change also makes parse_error callback not function.
It probably be removed from API.

Tatsuhiro Tsujikawa 8317559090 nghttp2_hd: Implement stream header inflater
This stream inflater can inflate incoming header block in streaming
fashion. Currently, we buffer up single name/value pair, but we chose
far more smaller buffer size than HTTP/2 frame size.
